Can u guys guide me through this, I'm looking at this thing and I don't know where to begin. The dealer said I had to take of the rear sprocket. And it looks like the rear sets and shift lever are in the way too. Thanks for any help with my Sunday project.

If you don't already own an impact driver for front sprocket removal I'd suggest having the dealer do the work for you (albeit minimal info provided). Otherwise you'll end up with an absolutely badass $300 DeWalt impact driver and still be stuck in this situation. Your time is probably more valuable, unless you really want to make a project out of it instead of riding. Best of luck either way.

Just changed my front sprocket last night, all you need is a 10mm allen on an impact driver. Of course if your not taking the chain off completely it would be impossible to get the sprocket out after you loosen the bolt. You def should not need to take the rearsets off.

The dealer who did mine stated there was a bracket in the way, 2 hours labour, cheap to have them do it at that.

Hmmmm, is my bike different. There is def no bracket in the way to get to the front sprocket. I have looked at every picture i have to see if maybe i removed it at some time, but def nothing there.

There will be like zero lateral movement in the chain, so you would have to loosen the rear wheel eccentric adjuster and pull the chain forward off the front sprocket. Thing is the clutch slave is in the way, so needs to come off I believe.

I did mine a few weeks back. PITA, but procedure was:

1) Lower LHS fairing off.
2) Clutch Slave off (three bolts - not actual entier removal off the hose!)
3) Remove Allen bolt (facing you) that connects shift rod to the gear change on the engine side
4) Remove sprocket cover
5) Loosen rear chain adjuster and give yourself as much slack as possible*
6) loosen off the allen bolts holding on the spar that the footrest attaches too - once done pull it towards you - BE CAREFUL, some of the bolts also hold the sidestand. You should be able to pull it towards you by 10mm or so.
7) Loosen the 10mm allen bolt in the sprocket shaft and remove sprocket (it'll still be fiddly and you'll swear alot).
8) Fit new sprocket -much easier than removal.
9) Tap bracket back in (I used a rubber mallet) and threadlock and retorque bolts (care as not all the torques are the same)
10) refit 4) to 1) above, torquing and threadlocking as you go.
11) Re-adjust chain tension.

*Be really careful with the LHS exhaust, as the loose chain will flop down and the pins can easily scratch the side of the exhaust - I wrapped the exhaust with a old towel.
